Roof ventilation comes in a variety of forms, but what are they and how do they work? We'll go over the many types of roof exhaust vents in this article.
Roof vents are divided into two categories: exhaust and intake
Exhaust vents exhaust hot air, while intake vents allow cool air to enter.
We'll go over the seven various types of roof exhaust vents in this article.
Roof ventilation is critical for a variety of reasons
Manufacturer Installation Guidelines:
When providing a homeowner with a manufacturer's guarantee, you must ensure that the roofing system is installed according to the manufacturer's specifications. They define proper roof ventilation within those limits. They may deny an otherwise covered claim if your roof is not properly ventilated!
Prevent Ice Dams:
Have you ever driven through Dayton during the winter and noticed enormous icicles hanging from a building's roofline? The trapped heat in the attic interior and the chilly surface temperature of the shingles on the exterior cause this. Ice dams can be avoided by using proper ventilation.
Mold Growth:
If your roof is not correctly vented, a lot of hot air will be trapped in your attic, particularly during the summer. Moisture comes with heated air, and most homeowners don't visit their attics very often, so it's usually gloomy. What kind of climate is ideal for the growth of mold? Moist, dark areas, you got it! Mold cleanup or abatement is expensive, so you'll want to do everything you can to avoid it.
Roof Exhaust Vents: 7 Different Types
Ridge Vent:
Roof exhaust ventilation of this sort is the most popular. This is the most efficient way to discharge hot air and is put at the top of your roof. (This is due to the fact that heat rises.) A ridge vent will almost certainly be included in a roof replacement quote. When replacing a roof, we will install a ridge cap once the ridge vent has been placed. The ridge cap is a thicker, more flexible shingle that protects the ridge vent by bending over. This is especially crucial in Dayton, Ohio, because of our climate.
Off Ridge Vents:
Off Ridge Vents are galvanized steel vents that are situated lower on the roof. Due to its size and lower installation point on your roof, this type of vent is not a viable primary vent. Your contractor may utilize this as an additional venting system if you have a small peak and can't run a substantial ridge vent.
Box Vents:
Box vents will, believe it or not, take on a square shape! Aside from the humor, these are very functional venting devices. They are usually 1.5 ft by 1.5 ft in size. Because of their modest size, they may be placed almost anywhere. They're especially beneficial on roofs with lower peaks when a ridge vent isn't feasible.
Powered Attic Vents That Are Hard-Wired:
As you might expect, these vents are hardwired and powered by electricity, allowing them to suck hot, stale air out of the attic. They are effective in removing hot air, although they do use some electricity in the process. If you choose this type of venting system, make sure it has enough power to keep the attic temperature in check!
Solar-Powered Attic Vents:
While these roof exhaust vent systems save money on electricity, they face the same problems as their hard-wired counterparts. As a result, we usually recommend keeping with a more traditional approach of exhaust vents.
Roof Turbines:
In the early 1900s, this roof exhaust venting device was developed. Wind speeds of about 5 mph are required to activate it. You can see how this could be an issue... Your roof will not have a venting source on those hot summer days in Dayton when there is no breeze and high temperatures. Ironically, this is when your roof's venting is most needed! As a result, we don't recommend roof turbine venting solutions.
Cupola Vents:
Cupola vents aren't seen very often. Installing them is difficult and costly. They work similarly to a box vent in terms of efficiency. The aesthetic appeal of the cupola vent is one of its main advantages. Their style can be used to complement the architecture of a property. A cupola vent may be right for you if you want glam over efficiency.
